5. Board Update Portal
Introduction
The Cyclone III LS FPGA Development Kit ships with the Board Update Portal
example design stored in the factory portion of the flash memory on the board. The
design consists of a Nios II embedded processor, an Ethernet MAC, and an HTML
web server.
When you power up the board with the PGM/USER LOAD switch (SW2.6) in the on
position, the Cyclone III LS FPGA configures with the Board Update Portal example
design. The design can obtain an IP address from any DHCP server and serve a web
page from the flash on your board to any host computer on the same network. The
web page allows you to upload new FPGA designs to the user portion of flash
memory, and provides links to useful information on the Altera website,
including
links to kit-specific and design resources.

After successfully updating the flash memory user design, you can load the user
design from flash memory into the FPGA. To do so, set the PGM/USER LOAD switch
(SW2.6) to the off position and power cycle the board.
The source code for the Board Update Portal design resides in the
Portal is corrupted or deleted from the flash memory, refer to
Device to the Factory Settings” on page A–4
to restore the board with its original
factory contents.

Before you proceed, ensure that you have the following:
A PC with a connection to a working Ethernet port on a DHCP enabled network.
A separate working Ethernet port connected to the same network for the board.
The Ethernet and power cables that are included in the kit.
To connect to the Board Update Portal web page, perform the following steps:
1. With the board powered down, set the PGM/USER LOAD switch (SW2.6) to the
on position.
2. Attach the Ethernet cable from the board to your LAN.
3. Power up the board. The board connects to the LAN’s gateway router, and obtains
an IP address. The LCD on the board displays the IP address.
4. Launch a web browser on a PC that is connected to the same network, and enter
the IP address from the LCD into the browser address bar. The Board Update
Portal web page appears in the browser.
